EXECUTRIX, OIE` GLENDALE, CALIFORNIA I CRUDE OIL DISTILLING APPARATUS n Application led April 5,

ing the quantity of crudeoil to be heated by the furnace and to provide means for causing the oil to pass over the vaporizing means in the Vform of a ilm, thereby requiring less heat tovaporize the oil than when the oil 1s vaporized in bulk.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to

1 be hereinafter fully described, illustrated in" the accompanying drawings and specifically pointed out in the appended claims'.

- 'In describing the invention in detail, reference will behacl tothe accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a diagrammatic sectional view of the apparatus. Figure 2 is a section on line 2 2 of Figure V1. c Y Y Figure 3 is a section on line 3-3 of Figure 1. y 1 f c Figure 4 is a section on line 4 4 of Figure1.'V f. M 1

Y yIn the drawings, A indicates'the heating apparatus which comprisesthe furnace 1 and the vessel 2. The furnace 1 is provided with the usual chimney 3, the lower part of whichV is Aformed with avcentral chamber 4 which leaves the passages 5 at thesides of the chimney. A plurality of U-shaped tubes 6 isar- Y ranged inthe vessel 2, one'limb of each tube being in communication withthe chamber 4, and'V the outer limby of each tube being in communication with one of thepassages 5. .Thus'the products of combustion from the ufurnace will pass into the chamber 4 and flow through the tubes into .the passages .5, from which they will escapej through .the

upper part of the chimney. The ilow of the products of combustion through the tubes will highly heat the same, as will be understood. A perforated partition 7 is arranged above the tubes and a perforated distributor plate 8 is arranged over this partition. Y

A tube 9 connects the vessel A with the vesselB, the tube being connected withthat end of the vessel A which is opposite the stack or chimneyand the tubes 6 terminate short of this end of the vessel. A partition 10 is arranged adjacent one endof vthe vessel B and divides the same into a'condensing chamber 11 and a vaporizing chamber 12.

The tube 9 leads the vapors from vthe vessel A into the chamber 11 ofthe vessel B and a pipe 13, containing a 'valve 14, connects the upper part of the chamber 11 with the chamber 12, so that the uncondensed vapors in chamber 11 will pass into the chamber 12. The condensed liquids, collecting in the bottom of the chamber 11, will pass through the tube 15, into a tank 16. The' vapors in chamber 12 willV pass through a tube 17 into the condensing chamber 18 of a vessel Dv which is constructed similarly tothe vessel B, the vapors in chamber 18 passing through apipe 19 containing a valve 20, into the chamber 21 of the vessel D and from this chamber 21, the vapors will pass through a tube 22 into a vessel E and from this vessel, the uncondensed vapors will pass through la pipe 23 to any desired point. A coil 24is arranged in the vessel E through which crude oil is pumped from any suitable source by a pump 25, and the vapors, contactingl with the coils 24 which contain the cold crude oil` will be condensed and the condensed liquids.l collectingV in the bottom of the vessel E. will pass into a tank 26 through arp-ipe 27. YThe oil passing through the coil 24 thus acts as a .condensing medium for the condensible vapors passing into the vessel E from the tube 22 and these vapors will heat the oilin the coils. The heated oil will pass from the coils through a pipe 28 into the bottcm part of the chamber 21 of vessel D. The level of oil in said chamber 21 .is-controlled by a float valve 29. A pipe-30 con-- nects the bottom of the chamber 21 with'a pump 31 and pipes 32 and 33 lead from the outlet of the pump, the pipe 32 delivering the oil into the top of the vessel D, Where it falls upon the perforated distributor plate 34 and passes through the perforated partition 35 and drops upon the V-shaped coils 36 which have their ends in communication With the condensing chamber 18, so that this oil is distributed in a film on the tubes ,36 Which contain the hot vapors so that some of 'the oil is vaporized and some of "the vapors 1n the tubes are condensed, .the condensed liquids iovving back into the chamber 18 and passing through the pipe 37 into a tank 38,. The pipe 32 is provided with a valve 39. Some of the oil from -the pump 31 Will pass through the pipe 33 into the chamber 12 of vessel B, in which the level of voil is controlled :by a flo-at valve 40, and the oil in vessel B is pumpe-d by a pump 41 to the Vtop part et thevessel B, the chamber 12 of which is lalso provided With a ,distributing plate., a perforated partition and the Veshaped coils, Vsimilarly to the vessel D. `Some ot ythe oil from the pum-p 41 is carried by the pipe 42 to the vessel A, the oil level in Which is regula-ted by a float valve 43, and a pipe 44 carries lsome of the oil to the top of the tank A, Where it passes through :the distributor pla-te 8 and the partition f7 upon the :coils 6.

Coils 4.5 are `arranged in the bottom of each of the tanks B and D for heating the oil therein, these coils being connected by :the pipes 4:6 with one another --and With `the vessel A, so that lthe hot .oil in the vessel A. will pass 4through A'the coils and will then pass from the coil in vessel D through the pipe 47 into the tank 48.

Thus it Will be 'seen that the :crude loil Will tirst be pumped into the coil 24, Whe-re it is heated from. the vapors entering the `Yvessel E .through the pipe .22 and then the oil will pass to the vessels D and B inally pass .t-o the vessel A. Some of 'the oii is pumped into the top part of each vessei A, B and D, where it ris distributed 4-in tilms on the coils 36 :in vessels D and B and on the coi-ls 6 in vessel A. Thus other portions of the oil :are vaporized in the vessel-s and the vapors pass from one vessel to another until the uncondensible vapors pass from the vessel. E through the pipe 23. The Ycondensed vapors are carried into suitable tanks from the condensing chambers in the vessels B, D and E.

From the foregoing it Will be seen that a large part of the crude oil is evaporated in vessel D and :another large part in vessel B. so that there is but a comparatively small part of the cil to be heated in the vessel A. rfhus the oil is vapo-rized with the minimum amount of'fuel.

By passing the oil over thetubes heated by the vapors in the term of a film, the oil is lquickly vaporized and with less heat than is required if the oil were heated in bulk.

rEhe following example is given of the operation oit' the device:

rlhe crude oil enters the coil 24 in vessel E at about 80o and passes from the coil at about 150". About 25% of the crude oil is vaporized in vessel D and passes into vessel E :at about 250. The residuum oil from vessel A flo-Wing through the coils in vessels B and D are about 450 so that the oil in vessels B and Dare heated by this oil and the vapors passing from vessel A to vessel B are about 45.0, While the vapors passing from vessel B to vessel D are about 3500. The vapors passing from vessel A to vessel B are about 8% of thetotal crude and the residuum oil .passing 'rom vessel A through the coils is :about 6% ofthe crude.

lt is thought. `from the foregoing description that the advantages and nove'l `features of the invention Will be readily apparent.

It is to be understood that changes may 'be rnade in .the construction and in the combination and arrangement of the several parts, provided lthat such changes fall Within the scope of the appended claims.
